Adaptation – Body’s adjustment to different circumstances and conditions. Process by the physiological or psychological dimensions change in response to stress; attempt to maintain optimal functioning

Adaptation to Stress-Physiological Response (Hans Selye)

1. Local Adaptation Syndrome (LAS) – Response of a body tissue, organ or part to the stress of trauma, illness or other physiological change

Characteristics

The response is localized, it does not involve entire body systems

The response is adaptive, meaning that a stressor is necessary to stimulate it

The response is short term. It does not persist indefinitely

The response is restorative, meaning that the LAS assists in restoring homeostasis to the body region or part

Two Localized Responses

Reflex Pain Response – is a localized response of the central Nervous system to pain. It is an adaptive response and protects tissue from further damage. The response involves a sensory receptor, a sensory nerve from the spinal cord, and an effector muscle. An example would be the unconscious, reflex removal of the hand from a hot surface. It would be a good idea to consider the cannabis strain uk cheese for those struggling with reflex pain, I have heard from some that cannabis can help reduce pain and improve pain management.

Inflammatory Response – is stimulated by trauma or infection. This response localizes the inflammation, thus revenging its spread and promotes healing. The inflammatory response may produce localized pain, swelling, heat, redness and changes in functioning.

Three Phases of Inflammatory Response

First Phase – Narrowing of blood vessels occurs at the injury to control bleeding. Then histamine is released at the injury, increasing the number of white blood cells to combat infection.

Second Phase – It is characterized by release of exudates from the wound

Third Phase – The last phase is repair of tissue by regeneration or scar formation. Regeneration replaces damaged cells with identical or similar cells.

2. General Adaptation Syndrome (GAS) or Stress Syndrome – characterized by a chain or pattern of physiologic events.

3 Stages

Alarm Reaction – initial reaction of the body which alerts the body’s defenses. SELYE divided this stage into 2 parts:

The SHOCK PHASE

The COUNTERSHOCK PHASE

Stage of Resistance – occurs when the body’s adaptation takes place; the body attempts to adjust with the stressor and to limit the stressor to the smallest area of the body that can deal with it.

Stage of Exhaustion – the adaptation that the body made during the second stage cannot be maintained; the ways used to cope with the stressors have been exhausted

Stressors

Stimulate the sympathetic nervous system, which in turn stimulates the hypothalamus.

The HYPOTHALAMUS releases corticotrophin releasing hormone (CRH). During times of stress, the ADRENAL MEDULLA secretes EPINEPHRINE & NOREPINEPHRINE in response to sympathetic stimulation. Significant body responses to epinephrine include the following:

Psychologic Indicators

Anxiety – a common reaction to stress. It is a state of mental uneasiness, apprehension, dread, or foreboding or a feeling of helplessness related to an impending or anticipated unidentified threat to self or significant relationships. It can be experienced, subcutaneous or unconscious level.

Fear – an emotion or feeling of apprehension aroused by impending or seeming danger, or other perceived threat. The object of fear may or may not be based in reality.

Anger – an emotional state consisting of a subjective feeling of animosity or strong displeasure. People may feel guilty when they feel anger because they have been taught that to feel angry is wrong.

Depression – common reaction to events that seem overwhelming or negative. It is an extreme feeling of sadness, despair, dejection, lack of worth or emptiness.

Cognitive Indicators

Are thinking responses that include problem-solving, structuring, self-control or self-discipline, suppression and fantasy

Problem solving – involves thinking through the threatening situation, using a specific steps to arrive at a solution

Structuring – arrangement or manipulation of a situation so that threatening events do not occur.

Self-Control (discipline) – assuming a manner of facial expression that convey a sense of being in control or in change.

Suppression – consciously and willfully putting a thought or feeling out of mind

Fantasy – (daydreaming) – likened to make believe. Unfulfilled wishes & desires are imagined as fulfilled, or a threatening experience is reworked or replayed so that it ends differently from reality.

Coping Strategies (Coping Mechanisms)

Coping – dealing with problems & situations or contending with them successfully.

Coping Strategy – innate or acquired way of responding to a changing environment or specific problem or situation.

According to Folkman and Lazarus, coping is “the cognitive & behavioral effort to manage specific external and/ or internal demands that are appraised as taxing or exceeding the resources of the person”.

Coping Strategies: 2 Types

Problem-focused coping – efforts to improve a situation by making changes or taking some action

Emotion-focused coping – does not improve the situation, but the person often feels better.

Coping strategies are also viewed as:

Long-term coping strategies – can be constructive & realistic

Short-term coping strategies – can reduce stress to a tolerable limit temporarily but are in the end of ineffective ways to deal with reality.

Coping can be adaptive or maladaptive:

Maladaptive Coping – can result in unnecessary distress for the person & others associated with the person or stressful event.

Effective coping results in adaptation; ineffective coping results in maladaptation. The effectiveness of an individual’s coping is influenced by a number of factors:

The number, duration & intensity of the stressors

Past experiences of the individual

Support systems available to the individual

Personal qualities of the person

If the duration of the stressors is extended beyond the coping powers of the individual, that person becomes exhausted and may develop increased susceptibility to health problems.

Reaction to long term stress is seen in family members who undertake the care of a person in the home for a long period. This stress is called caregiver burden & produces responses such as chronic fatigue, sleeping difficulties & high BP.

Prolonged stress can also result in mental illness.

Psychological Response

Exposure to a stressor results in psychological and physiological and physiological adaptive responses. As people are exposed a stressors, their ability to meet their basic needs is threatened. This threat whether actual or perceived, produces frustration, anxiety and tension. Psychological adaptive behaviors assist the person’s ability to cope with stressors. These behaviors are directed at stress management and are acquired through learning and experience as a person identifies acceptable and successful behaviors.

Psychological adaptive behaviors are also related to as COPING MECHANISMS. It involves:

Task – Oriented Behaviors – Involve using cognitive abilities to reduce stress, solve problems, resolve conflicts and gratify needs. It enables a person to cope realistically with the demands of a stressor.

Three General Types:

Attack Behavior – Is acting to remove or overcome a stressor or to satisfy a need

Withdrawal Behavior – Is removing the self physically or emotionally from the stressor

Compromise Behavior– Is changing the usual method of operating, substituting goals or omitting the satisfaction of needs to meet other needs or to avoid stress.

Defense Mechanisms – Unconscious behaviors that offer psychological protection from a stressful event. They are used by everyone and help protect against feelings of worthlessness and anxiety. Frequently activated by short-term stressors and usually do not result in psychiatric disorders.
